Hmmm... just tried the setings you gave on one of my own presets and I'm not hearing any crackling and the dry/wet control is available. Odd. Name a preset that has the problem and I'll try it on my machine.

I followed these steps but am not getting any crackling. I am listening through headphones plugged directly into the Origin and have the volume turned up all the way. Are you listening through the headphone output or the master out? Are you listening directly to this output or do you have it plugged into a DAW or some kind of mixing board, etc.? What is the volume setting you are using (Origin Master Level or Headphones level)?

The reason for the delay crackling is within cubase (studio 5). The delay parameter sync = ON at origin in a MIDI-Track in cubase makes it crackling. If i turn delay sync off, the crackling stops immediately.
